I have talked about changing your think into a thunk before. What I mean by this is learning to think differently about money. For my personal journey, I remember literally having to change from a poor mindset into a wealthier one. Here is a chart that talks about different mindsets in different social classes from the book Bridges Out of Poverty. I hope you can read it easily.
So, hopefully you can use this chart to challenge your thinking a bit and find out where you fit. If you think poor, you can work on changing that mindset a bit.
